Background & objective: The response of plants to urea and zinc foliar spraying has been widely studied, but similar research on medicinal and aromatic plants is limited. Due to the fact that the changes of black cumin essential oil in response to the application of urea and zinc in different planting dates have not been evaluated, in this research it is tried to determine the effect of foliar application of zinc and urea chemical fertilizers in the two seasons of autumn planting and Spring is on vegetative traits, chlorophyll, percentage and yield of black cumin essential oil (Nigella sativa L.).
Methods & Materials: The experiment was performed as a split-plot based on a randomized complete block design with three replications. In this experiment, planting season as the main factor (autumn planting in early November and spring planting in early May) and foliar treatment were placed in sub-plots.
Results: The results showed that the highest plant height was related to autumn planting with an average of 36.8 cm.
Conclusion: The application of urea chemical fertilizer at the rate of 50 kg/ha was the main factor in increasing the average of the studied traits among the nutritional treatments. In general, in conditions similar to this experiment, it is recommended to use urea fertilizer and autumn planting to obtain the desired essential oil yield in black cumin.
